Swap the Primary Storage Center for a Live Volume

If the secondary Storage Center is receiving more I/O for a Live Volume than the primary Storage Center, swap roles to improve performance. If an outage is planned at the site where the primary Storage Center is located, swap roles before the outage to make sure there is no interruption to volume availability. After swapping roles, save restore points to make sure that the restore point for the Live Volume stays current.
